11 Claims.

This invention concerns a closure for containers. more particularly a closure or cap which directly-engages uponthe neck of a bottle or collapsible tube or upon special means provided 5"; for in connection with any container.

The principal object of this invention is to provide for a closing cap which'isopened by lifting it,- straight or-along an irregular path; said cap remaining however-on the container, whether 20 plurality of seals. All these .seals are broken by simply shifting the cap.

Another important feature is that the closure or cap is' manufactured in a simple operation which is eminently adapted for quantity protec- 5 tion. This cap of my. invention may be shaped out of sheet material by a simple punching, Dressing and/or drawing operation.

This invention is closely related to the subject matter of a prior patent application filed by me on September 24, .1934,J-underf Serial=No. 745,274, .Patent No. 2,112,125, entitled Closure and is a continuation in part of the said patent application.

I While to some extent the subject matter of said prior application overlaps withthe present appli-- cation, the article of the said invention is improved upon by the departure therein described, e. g;, a closure struck-up from a single piece of sheet material. 4

The invention will be explained by way of illus trative egamples, which readily lend themselves to elaboration and modification within the knowledge of the art.

In the accompanying drawing: v Fig. 1 shows a front elevation of a and closure of my invention.

Fig. 2 shows'a corresponding side view, partly in section.

In Figs. 1 and 2 the closure is fully closed.

45 container The fully sectioned views ofFlgs. 3"and4 jcorrespond to the view of Fig. 2; but in these views the closures are fully and partly open, respectively. 1 Fig.5 shows atop view of a closure of my 55 invention. V 1

In respect to the last mentioned object, I have 7 throughout the various views:

my invention is supplied, it is understood that .when the closure is closed. The washer may into the bore of the neck and slidably fits into the bore l6.-

PATENT OFFICE Fig. 6 shows a corresponding cross-sectioned side view. p v

The closures of Figs. 5 and 6 areslightly modified as compared with the closures of the preceding figures, inasmuch as in these figures the 5 openings or perforations are angularly displaced from the guide means to the extent of 90". In the preceding figures the openings and the guide means were in alignment.

Fig. '7 shows the elevation of the neck part of 10 a container of my invention.

Fig. 8 shows a corresponding view of a modification of my invention in which the guide groove is helically disposed.

Fig. 9 is a similar view of another modification. 16

Similar numerals refer to similar parts Whereas in the views of the drawing I showin all instances a bottle to which the closure of the container may assume various shapes, e. g.,

of a. collapsible tube. A neck suited. to receive the closure of my invention may be attached to any container. But in the drawing the neck II is shown to form an integral part of the con- 55 tainer l2. 1

The container and closure may be made out of any kind of preferred material. In the lightof the introduction I prefer to use a ductile, yield-' able elastic sheet material for the closure. Thus 80 the closure l3 of Figs. 1, 2, 3 and 4, and closure ll of Figs. 5 and 6 may be stamped, pressed and/or drawn out of sheet metal.

I provide a washer l5, made for instance out of cork or rubber, at the bottom of the closure, which is sealed against the top of the neck ll be frictionally retained in the closure, or may be fastened by an adhesive at thebottom of the closure. A cylindrical outer part of the closure slidably fits'overthe outerlcircumference of the neck ll of the container.

The central part of theclosure is depressed the bore It. The entrance of the bore is shown to be countersunk in the drawing. Thus I provide a concentric recess H in the neck, and the central, depressed part of the closure is shaped to fit not only into the bore but also intothe recess I1. The first step l8 of the depressedpart 5 of the closure fits against the side and bottom of the recess l1, and the second, central depressed step. the part I! slidably depends into and fits Thus, when the bottle'is closed, I provide a ,5

multiple seal: The cylindrical outer part of the closure seals against the outer circumference of the neck II; the top of the closure, by way of the washer l5, seals upon the top of the neck ll; 5 the sides and the bottom of the outer depressed part of the closure, the first step l8, seal against the vertical part and the horizontal part of the angular recess or counterbore ll, respectively; finally, the vertical, shank part of the second steplfl abuts upon the bore I6 01' the neck.

'I'he closure is-raised or lowered for the purpose of opening or closing the bottle. When the closure is raised from the positions of Figs. 1' and I 2, into the position of Fig. 4, the various seals, which were Just mentioned in the preceding paragraph are broken, until finally an Opening 2| in the cylindrical outer wall of the closure, 20, which is shown in-the drawing as a rectangular perforation, rises above the top level of the neck so that the liquid contained in the bottle may be poured out of the bottle through the said opening, the dispensing speed being controlled by the extent to which said opening clears the top of the neck, 1. e., it depends on the amount for which the closure has been raised.

Another perforation or opening, a slot 22, is disposed upon the opposite side of the closure. The opening 22 is narrower than the opening 2| and it registers only with the lower part of the opening 2| Whereas slot 22 is closed by the outer circumference of the neck I l in the view of Fig. 4, the said slot will open when the closure is raised more, into the position of Fig. 3. When thecontents of the bottle or container l2 are being poured forth through the opening 2|, air will be allowed to enter the closure and into the bottle or containerthrough the slot 22. Thus' the'partial vacuum created upon the inside of the bottle by dispensation of the fluid through the opening 2|, will be overcome by the air entering through the slot 22, so that the fluid flows more freely and faster. Thus the dispensation of a liquid from the container or bottle cannot only be controlled by increasing the opening 21 when raising the closure at the beginning of the operation, but the dispensation is further facilitated, when the slot 22 emerges above the top of neck II and admits air.

It is one particular advantage of this invention, that the closure does not have to be fully removed from the bottle or container in order to allow dispensation. also go further,-and provide a catch upon the closure which engages upon a protruding or receded part of the neck, and which prevents the closure from being completely groove in the outside of the neck ll. Thus I provide grooves 23 upon opposite sides of nebk ll." Near the lower end of the outer cylindrical part 2| of the closin-e I provide a depression 2|, which extends into the said groove 23. The depressed part 24,:slides up and down in the groove 22, when the closure is raisedor lowered. This facilitates the dispensing motion from the positions of Figs. 1 and 2 through an intermediate position of Fig. 4 into the position of Fig. 3. But, since the groove does not extend all the way up to the top of the neck II, the closure cannot completely be .removed from the container or bottle. r purposesof illustration, the openings or w tions 2| and 22 and the groove and deare all shown in alignment in the first uch alignment is not necessary. In-

= circumference of prising in combination with the neck of a constead of a straight groove/I may also provide a helical groove 25 as shown in Fig. 8. This arrangement may be used, when a twisting motion is preferred to an up and down motion during the operation of opening the bottle or of closing 5 it. If the helix is sufficiently inclined, the closure is locked by wedge action in the closed position.

At the upper end of the helical groove 25, I may provide a straight upward extension 26 which allows the removal of the closure or container. An oppositely or horizontally tilted 1 extension 21 may be provided for at the lower end of groove 25 or of groove 23, the tilted extensions permitting the locking of the closure in the closed position, in analogy to a bayonet lock (Fig. 9). 1

Although I have shown and described one form of embodiment of my invention in detail, yet I do not wish to be limited thereby, except as the state of the art and the appended claims may require, for it is obvious that various modifications and changes may be made in the form of embodiment of my invention, without departing from the spirit and scope thereof.
